Abstract (en)
[origin: WO2018134633A1] The method comprises: (a) obtaining (300) a first time series of a first well parameter from the first well and a second time series of a second well parameter from the second well, (b) processing (310) the first time series to obtain a processed first time series, (c) filtering (320) the second time series by removing dynamic variations from the second time series to obtain a filtered second time series representative of static variations of the second time series, (d) determining (330) a correlation between said processed first time series and said filtered second time series at various time shifts between said processed first time series and said filtered second time series, and determining a maximal correlation coefficient and a time shift at maximal correlation between said processed first time series and said filtered second time series, the maximal correlation coefficient being representative of the connectivity between the first well and the second well.
